GAS HEAT-RADIATOR.

Application filed July 8, 1916.

To all whom it may concern.'

Be it known that l, AUGUST J. HARTFIELD, a citizen oil the United States of America, residing at Los Angeles, county of Los Angeles, State oi California, have invented a certain new and useful Gas Heat-Radiator; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in gas heat radiators; more particularly to improvements in the construction disclosed in my Patent No. 1,181,382, dated May 2, 1916.

One object of the invention is to provide in the combustion chamber a line which is so formed and arranged that when the burner is lighted the air in said flue is quickly heated and consequently rarefied so that it moves out of the flue and thus facilitates the movement of the products of combustion from the combustion chamber to the outlet of the radiator.

Further objects of the invention are to provide a novel and improved gas heat radi ator which is highly practical and serviceable, clean and odorless in operation; economical, convenient, and lsanitary in use, and efficient in action.

Other objects and the advantages of the invention will be apparent to those skilled in the art from a careful consideration of the following description of the preferred construction embodying the invention, taken in connection with the accompanying drawings in which- Figure 1 is a front elevational view of the improved gas heat radiator; Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1; Fig. 3 is a broken sectional view taken onthe line SMB of Fig. 2; Fig. 4 is a broken side view of the lower part of the combustion chamber; and Fig. 5 is an elevational view of the hood.

As shown in the drawings, the central burner section or combustion chamber 7 is provided in the upper and lower parts thereof with side openings or ports 8 into which latter are fitted the nipples 9 whereby the combustion chamber 7 is connected to a plurality of radiator sections 10 which are disposed on each side oi the combustion chamber 7 and are connected by the nipples 9 tted in the usual ports which are pro- Speccaton of Letters Patent.

Serial No. 108,099.

vided in the upper and lower parts ot the radiator sections 10.

llithin the lower part of the combustion chamber 7 is arranged the burner 11 to which is connected one end of the pipe 12 which passes through an opening 13 in one side of the combustion chamber 7 and has on its other end the Haring fitting 14 into which extends the gas fuel supply piping 15v Vchamber 7 provided with openings or vents 22. rlhe passageways 11 in the upper party of the burner 11 preferably extend substantially parallel to the inner wall of the hood 20 so that the gas flame is directed away from the inner wall of the hood and toward the opening in the top end oi the hood. To permit access to the burner 11 and the placing of the hood 2O on the ledge 18, a door 23 is provided at the lower front part of the combustion chamber 7.

The combustion chamber 7 is provided with the waste gas flue 24 which is in communication with the ports 8 in the lower part of the combustion chamber 7 and eX- tends upwardly above the burner 11 and as shown is so formed and arranged that when the burner 11 is lighted the air in said flue is quickly heated and rarefied so that it moves out of said iue and thus causes a quick movement of the products of combustion or waste gas from the combustion 'chamber 7 to the outlet 25 of the radiator.

In this instance the partition wall 26 divides the central burner section 7 into the combustion chamber and the waste gas oiftake iiue 24. The central burner section 7 is provided with an air inlet port 27 in its lower part below the burner 11. A pipe or duct 28 is connected to the outlet 25 and adapted to carry off the products of combustion from the flue 24 to the outside of the building in which the radiator is installed. y

From the foregoing description the operation and advantages. of the improved gas heat radiato-r Will be apparent toy those skilled in the art. When the burner 11 is lighted the air in theA iue 24 is quickly heated and rare'ed and its back pressure is so reduced' as to cause a quick movement of the products of combustion from the combustion chamber 7 to the outlet 25. The heated products of combustion pass from the burner l1 to the upper part of the combustion chamber 7 and thence pass downwardly through the sections 10 and thence through the flue 24 to the outlet 25 and pipe 28. Then startingto operate the gas heat radiator the latter is filled yWith cold still air which causes a back pressure and consequently a clicking effect on the iiame of the burner 11, ybut the vents 22 permit the egress of a portion of the cold air so that the heated products of combustion are enabled toquickly force their Way through the radiator and remove thev still air. When the radiator is in full operation some air is drawn into the radiator through the vents 22, The hood or battle plate 20 shields the burner 1l from back drafts due to gusts of Wind by deflecting the back drafts through the vents 22 and thus it prevents putting out of the lire in the combustion chamber 7.

The construction which has been particu-- minor changes and modifications, Wherefore the right is reserved to all such changes and modications as do not depart from the spirit and scope of the invention Which is defined in the appended claim.V

A Ventilating gas heat radiator comprising a central burner section having a partition Wall dividing the same into a combustion chamber and a lWaste gas oiftake 'Huet a gas yburner disposed in the lower part of the combustion chamber, a battle plate arranged above said burner and provided with upwardly converging Walls and having an open top, said central burner section having an air inlet port below said burner and having auxiliary air inlet ports opposite the balfleplate, a plurality of radiator sections arranged at the sides of the central burner section and connected so that at their upper parts they are in open communication with the upper part of said combustion chamber and attheir lower parts they are in open communication With said Waste gas oiftake iiue. Y

` In testimony whereof, l have signed my name to this specification at Los Angeles, county of Los Angeles, State of California, this 30th day of June A. D. 1916.
